Winklebury Sand Mastic
We cover Winklebury for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Mastic worn away on windows facing the weather
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
Looking after it afterwards
Aftercare is simple:
- Take care around the mastic when scraping paint
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

We will help you decide. Period homes often look best with sand mastic, and modern sealants suit newer frames.

What sand mastic looks like in Winklebury
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as The Vyne (about 3 miles north-east) nearby, there’s older building stock in the area around Winklebury as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Castle Hill Infant School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Basingstoke station, any sash windows need sound mastic to keep draughts and rain out.

How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Parking around Winklebury is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
- Mention any parking rules near the property

- Crumbling stone or brickwork round the window
- Decisions on consent for listed homes
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.

Why it’s worth doing now in Winklebury
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Homes in smaller places like Winklebury can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- An ARBOMaster approved applicator
- Every job guaranteed for a year
- 20+ years of sealant experience
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
